Here's how to set one so there will be one less thing you need to touch your stinking mouse for:
- In Visual Studio, select Tools Options. Select Environment Keyboard.
- In "Show commands containing", enter View.TfsSourceControlExplorer.
- Map this to whatever keyboard command you want! If you want this command to be available anywhere in VS, make sure "Use new shortcut in" is set to Global. I mapped this to Ctrl+F8, which surprisingly was not mapped to anything.
- I then mapped View.TfsPendingChanges to Ctrl+Shift+F8.
I have to give a shout out to the free SlickEdit Gadgets addin, which has a Command Spy window which made it very easy to find which commands I needed to map.
